Description

SC-3000 GAME CART 32-48KB

SC-3000 GAME CART 32K-48K

This is a PCB specifically made to generate cartridges for the Sega SC-3000, SG-1000 and I believe also the Sega Mark III and Sega Master System (Japanese). It uses the standard 27C256 32KB EPROM. A secondary 32KB EPROM is optional to reach 48KB (only first 16KB are used). Nothing else is needed. The 2x 0.1uF disc capacitors are the standard 25% tolerance 16V (even 25V) one used in almost all electronics of the time. GAME MEMORY MAP is $0000-$7FFF with 1 EPROM and $0000-$BFFF with 2 EPROMs (the second one is mapped from $8000-$BFFF).
